The paper focuses the attention on the reverberation chamber method for shielding properties evaluation of equipment-level enclosures. The whole testing situation, chamber plus enclosure under test, is numerically modeled by a in-house FDTD code able to predict the field inside the enclosure and the voltage captured by probes placed inside it. After the code validation, the effect of the probe position, on the enclosure shielding effectiveness, is examined. In particular a field normalization is introduced in the shielding effectiveness definition. Finally, the effect of a frequency stirring application is also investigated.

Abstract
The paper focuses the attention on the reverberation chamber method for shielding properties evaluation of equipment-level enclosures. The whole testing situation, chamber plus enclosure under test, is numerically modeled by a in-house FDTD code able to predict the field inside the enclosure and the voltage captured by probes placed inside it. After the code validation, the effect of the probe position, on the enclosure shielding effectiveness, is examined. In particular a field normalization is introduced in the shielding effectiveness definition. Finally, the effect of a frequency stirring application is also investigated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
